Context : By studying young open clusters , the mechanisms important for star formation over several Myr can be examined .
For example , accretion rate as a function of rotational velocity can be investigated .
Similarly , sequential star formation triggered by massive stars with high mass-loss rates can be studied in detail .

Aims : We identified and characterized probable members of NGCÂ 6383 , as well as determined cluster parameters .

Methods : New Strömgren uvby CCD photometry , obtained by us , is presented .
This new data , together with Johnson UBV and 2MASS data in the NIR , was used to investigate characteristics of pre- as well as zero age main sequence cluster members .

Results : We present Strömgren uvby CCD photometry for 272 stars in the field of NGC 6383 and derive its reddening , E ( b - y ) = 0.21 ( 4 ) mag , as well as distance , d = 1.7 ( 3 ) kpc from the Sun .
Several stars with NIR excess and objects in the domain of the classical Herbig Ae/Be and T Tauri stars were detected .
Two previously known variables were identified as rapidly-rotating PMS stars .
The field population is clearly separated from the probable members in the color-magnitude diagram .

Conclusions : NGCÂ 6383 is a young open cluster , with an age of less than 4 Myr , undergoing continuous star formation .
True pre-main sequence members might be found down to absolute magnitudes of +6 mag , with a variety of rotational velocities and stellar activities .
